Low-level tester test requires the tester as a pod hanging under the helicopter, able to adapt to a variety of harsh natural conditions and used to test a flight components of sea clutter environment. In aid of PC104 embedded system and standard C++ language, a program is designed according to the requirement of low-level tester data acquisition. The system uses I / 0 to control the power board powering to the signal timing, A / D card real-time Signal acquisition, the altimeter return a high degree of data through the serial port. The article focuses on low-altitude tester software and hardware system design, given a set of test data to verify the effectiveness of the monitoring and control procedures. Field applications show that the system has the features of reasonable design, simple, accurate test to meet the design requirements.
